ATTACHMENT FOR SMOKING DEVICES Filed March 27, 1934 J y 7 ATTORNEY Patented Aug. 9, 1938 ZFFEQE 13 Claims.

This invention relates to improvements in smoking devices, such as pipes and cigar and cigarette holders, and more particularly to means for treating and directing the flow of smoke during its passage from the point of origin to the mouth of the smoker.

It is an object of this invention to cool and clean the smoke by providing a device having a combined cleaning and baffling element, thereby ;increasing the length of the path of flow of smoke from tobacco to mouth.

Another object is to provide a device of the character described having a combined positioning and closure means to adjust the position of the cleaning and baffling element and to close one end thereof.

Another object is to provide a device of the character described in which the said cleaning and baffling element is readily replaceable.

Other and further objects of this invention will be apparent from the drawing and the following description and claims.

The assembly of the remaining elements to complete the pipe stem is also indicated.

Similar numerals refer to throughout the several views.

Referring to the drawing in greater detail, a device constructed according to the present invention may comprise a bit or mouthpiece I having a smoke passage l therethrough. An outer tubular member 2 is mounted, preferably separately, as by a threaded joint, on one end of the mouthpiece. The opposite end of the tubular member 2 is mounted, also preferably by an easily separable connection, on a tobacco holding member, such as cigar or cigarette holder 3 or pipe bowl 3. An inner tubular member 8 is mounted in the rear end of the member 3, the smoke passage 9 through the member 8 forming a continuation of the smoke passage I through the member 3. Spacing means Iii, which may suitably be in the form of notched radial fins, are mounted on the member 8, preferably at or near the end connecting with member 3. An intermediate tubular member ii is positioned around the member 8 and is spaced therefrom and preferably also from the end of the member 3 by the spacing means It. The inner surface of this member ii makes an easily separable connection, preferably a loose frictional contact, with the spacing means it so that on disassembling the device this member is removed with the inner tubular member 3 and may then be easily detached therefrom, preferably by giving member 3 a slight jar or shake to avoid having to touch the member M. This member ll becomes soiled in, use, and may be readily removed and replaced with a fresh member whenever desired.

similar parts This member is preferably a cylinder having a diameter greater than half the inside diameter of the outer tubular member 2, in order to permit its ready alignment and closure by the means illustrated. These comprise a tubular member 5 having a closed outwardly projecting conical end of a maximum diameter greater than the inside diameter of the member ii and preferably less than that of the outer member 2. The end of the member l I is closed by being pushed against this conical surface when the device is assembled. The member 5 is preferably mounted in the end of the mouthpiece l in such manner that it is a continuation of the smoke passage 4. Suitable means for the passage of smoke from the space between the member l l and the outer member 2 into the smoke passage l of the mouthpiece i may comprise preferably one or more holes 6 in the member 5 between the points of contact with the member H and the mouthpiece I, although the smoke passage 4 may connect directly with this space, if desired.

While the device has been illustrated with the inner tubular member 8 connected with the tobacco holding member 3 and the member 5 connected with the mouthpiece I, it is recognized that these positions may be reversed, member 8 being mounted in mouthpiece l and member 5 in member 3, without departing from my invention. The flow of smoke will then be reversed in its passage through the device, as will be understood. The manner of assembly illustrated is preferred, however, as it will be found to be cleaned more readily.

The manner of adapting the device for use with a pipe, as illustrated in Figure 10, in which the spacing means I0 is continued as a screw IU of sufiicient length to engage both the outer member 2 and the stem of the pipe bowl 3', may also be varied, and any other suitable connection may be used as desired. For example, the projecting end of the member 8' may be in the form of a slightly tapered cylinder, making a tight frictional connection with a similarly shaped recess in the stem of the pipe bowl 3'.

The intermediate tubular member H may also be closed at one end, as illustrated by I in Figure 10. In this case the alignment and closure member 5 may be omitted, or it may be used simply as a spacing means 5a for positioning the closed end of the member ll. Figure 10 shows a section through one of three spacing means 5a which may be made as a part of the mouthpiece. The smoke passage l will connect directly or through suitable openings in the spacing member 5a, with the space between member II and outer member 2.

The member ll serves to clean and cool the smoke by increasing its path of flow through the device and by the reversals of flow caused thereby which tend to throw out dust, droplets of moisture and other non-gaseous matter suspended in the flowing gas. This purifying action may be increased by constructing the member ll of a suitable absorptive material, which may even be somewhat pervious to gas. For example, it may be made so that at least one surface, inner or outer or preferably both, is made of absorptive paper, decolorizing carbon, or other materials having similar functions. The flowing gas may also be filtered by placing a suitable filtering medium, such as loose cotton, in the annular spaces inside or outside this member, or both. It has been found, however, that such filters, even when loosely matted, are difiicult and inconvenient to insert and cause objectionably high pressure drop in use. A preferred filter may be prepared by attaching the ends of relatively short fibres to the surface of the member II. The fibres then extend into the flowing stream of gas and serve to filter and cleanse it of absorbable matter without unduly increasing the pressure drop through the device. The fibres are preferably of such length that, when attached, they extend in their normal form, which may be straight, coiled or kinky, from the surface of the member H a distance about that of the width of the annular space in which they are to be when the device is assembled. Then, if they become moist in use, they mat against the wall to which they are attached and are withdrawn at least partly from the flowing gas stream. Various modifications of member II, in which fibres are attached to the outer, inner and both surfaces of the member are illustrated in Figures 5a, 51),

and 50 respectively. The fibres may consist of cotton, wool, silk, hemp, wood pulp, rayon and other natural and synthetic fibrous materials. They may be attached to the surface of the member II by any glue or cement suitable for the intended use or by other means, or they may be made a part of the surface by being mounted therein during its formation. A suitable method particularly for obtaining fibres attached to the inside surface is to apply the fibres to a sheet of material, suitably paper, which is then rolled and formed into cylinders of desired diameter and length. The fibres may be caused to stand out from the surface to which they have been attached, in the desired manner, by imparting an electrical, preferably an electrostatic, charge to them while the adhesive is drying or setting. They may also be used in the form of a fabric, such as a chenille or a transparent velvet, which has numerous fibres with loose ends projecting from the surface of the fabric. Such fabrics may be strengthened and the back of the fabric made more rigid by application to one or both sides of a sheet of paper, Cellophane, or other suitable material. Or sugar water or a solution of a suitable hard resin in a volatile solvent may be applied the back of the fabric and allowed to set preferably after the cylindrical form has been prepared.

While the invention has been illustrated and described herein in its preferred forms, it is to be understood that it may be used in other forms, embodiments and modifications without departing from the spirit thereof. This invention is not to be limited to any examples, applications or explanations, all of which have been presented herein solely for purposes of illustration, but is limited only by the following claims, in which it is desired to claim all novelty insofar as the prior art permits.
